Our bodies are a complex collection of numerous biological cycles and systems that can often be difficult to fully understand. The body’s set of defense mechanisms constitute one such system. They protect us from harm 24 hours a day, seven days a week, from a whole number of things that could potentially harm us.
Here are fascinating things your body does which you may not have even realized were ranked among those defense mechanisms.
When we yawn, the body may be trying to get oxygen to the brain to prevent it from overheating. It also may need oxygen to keep a person awake.
The pathways for physical pain eventually evolved to include emotional pain. Our body experiences heartbreak so we can mark events in our life to try to learn from them.
When the body feels motion but cannot see it, it assumes the body has eating something poisonous. That's why it induces vomit to try to remove the non-existent poison.
When we feel a chill, our bodies hair follicles stand on end. This is because, when we had more hair, our bodies needed to prevent heat loss.
Scientists believe your fingers and toes get pruney when wet to give you extra grip. That makes sense.
Tickling activates the part of our brain that senses pain, which is why we try to fight off someone tickling us. We laugh to show submission.
We get sunburns because our body is sending blood to the dermis to protect against UV rays. It's a painful way of reminding you to wear sun screen!
